Ficus, Moraceae, Ailanthus. There are Indian figs, Thai figs, yellow figs, alpine figs, weeping figs and other tree species. Banyan is tall and majestic, self-propagating, rooted evergreen, and is a unique tree species in the subtropical zone. Strange air roots conjoined growth The air roots of banyan trees are inextricably linked and look like a long beard fluttering in the wind. As beautiful as a weeping willow. Air roots are adventitious roots sprouting from dry branches and exposed to the air. They have strong vitality, rely on the nutrition of the mother and can absorb moisture and nutrients in the air, and continue to extend downward. Some grow vertically downward, while others extend around branches. The growth point (white spot) at the tip of aerial root extends into the soil, and the aboveground part quickly grows into a root system, and the aboveground part grows into a trunk. The drooping air roots take root in the soil and become stems, which look like pillars. When the top growth point extends into a decaying tree, or meets a tree hole with foreign soil, or the epidermis is damaged or partially decayed, the air roots wrapped around the branches can grow. Roots grow first, then shoots grow, and leaves are regenerated. These many air roots vary in thickness and their branches are intertwined. Like vines, they are born from the same root and connected by blood. This "conjoined growth" is the most unique phenomenon in the woody plant world. It is difficult to break the age of several generations of a tree under one roof. Usually, trees with germination ability will germinate the next generation of plants from roots or stumps after natural death, and there are only the same generation of plants on the same tree at the same time. But before the banyan tree dies and rots, it can reproduce the next generation of trees through its air roots, and then the third generation of trees can reproduce on the second generation of trees through its air roots. These numerous trunk bodies can be separated or connected together to form a "big family". These changes in growth and reproduction were all carried out on the "original tree" in the same period, so that the same ancient banyan tree had different trunk generations, and the spectacle of "multiple generations living under one roof" appeared. For natural or unrecorded ancient banyan trees, it is difficult to find its age, especially the "ancestral age" of the tree. According to the convention, the oldest tree trunk, the oldest generation and the oldest tree age (with the most rings) should be regarded as the age of ancient banyan trees. The trunk of a single tree is thick, the crown is stretched, and the branches are flourishing. For example, an ancient banyan tree in Fuzhou Forest Park, Fujian Province, with a crown covering more than ten acres, has become a world of shade, which is really "banyan tree shade for half a day" and can be called China banyan king. A big banyan tree on the new island of Xinhui River in Guangdong Province has grown into a forest, full of cranes and storks, becoming a paradise for birds. The ancient banyan tree, the king of Macao trees, has experienced vicissitudes and is vigorous and awe-inspiring. Banyan is a kind of tree in Fujian Province, and Fuzhou is called Banyan for short. In Fujian, there are countless ancient banyan trees standing alone in the forest. The rooted landscaping banyan tree is well developed, magical and changeable, and has a unique shape. It is a characteristic of Ficus microcarpa cultivation to shape various bonsai and landscape trees mainly with roots. Ficus culture, Ficus horticulture, banyan bonsai, is splendid. Huge underground roots often emerge from the ground with spectacular shapes, such as natural root carvings. The air roots on the tree are wrapped around the trunk, turning into winding giant vines hovering around the tree, creating the spectacle of "Dragon Column". The roots of banyan trees cover an area and the scenery is charming. For example, the gate of China Folk Village in Beijing is a magnificent and moving landscape of a huge ancient banyan tree. The roots of banyan trees in Qiaotou Village, Chaoyang Town, Zhangzhou City, Fujian Province are intertwined for 2 kilometers, making it the longest and most magical "banyan root wall" in China.
